Together AI opens MiniMax M3.1 Flash for post-training

Together AI says MiniMax M3.1 Flash is now available for post-training on its platform. According to Together, users can run supervised fine-tuning (SFT) or reinforcement learning (RL) with their own data, rewards and environments, while keeping the training loop in their own Python code.

MiniMax replied to the announcement, thanking Together for "bringing LoRA-based post-training" to the model. MiniMax published the model's weights on October 22.
